Privacy Policy

1. Introduction

Welcome to Mi Isla ("the App"), developed and operated by Believe PR, owned by Armando Jimenez. Mi Isla is the boricua-first place to see what is happening in Puerto Rico: weather, official alerts, earthquakes, Sahara dust, air quality, the sea and beaches, rivers and flooding, and precipitation radar — in Spanish and English, free at its core.

We built Mi Isla to be useful without being nosy. The App has no accounts and asks for no personal information. This Privacy Policy explains exactly what the App does and does not do with data.

2. Information We Collect

Mi Isla is designed to collect as little as possible. We do not operate a server that stores your information, and we do not maintain a profile about you.

2.1 Information You Provide

Everything below is stored only on your device:

• Your municipio: If you choose your town manually (or confirm the one detected from your location), that choice is saved locally to scope the weather and alerts you see.
• Preferences: Your language (Spanish/English), theme (light/dark/system), units (temperature, wind, wave height), and notification choices are stored locally.
• App activity used for the review prompt: A simple on-device counter of calm interactions, used only to decide when to politely ask if you would like to leave a review. It never leaves your device.

2.2 Information Collected Automatically

• Approximate location (only with your permission): If you grant location access, the App reads your device location while you are using it to find your area. See Location Data for the full detail.
• Cached data: Weather and alert responses retrieved for your area are cached on your device so the App works quickly and offline.

2.3 Subscription Information (RevenueCat)

If you purchase Mi Isla Premium, our payments provider RevenueCat processes:

• Anonymous App User ID: A random identifier for managing your purchase. It is not linked to your name or identity.
• Subscription Status: Whether you have an active premium entitlement, so premium features unlock.

2.4 Information We Do NOT Collect

We explicitly do NOT collect:

• ❌ Personal identification (name, email, phone number, address)
• ❌ Usage analytics or behavioral tracking of any kind
• ❌ Crash or diagnostic reports sent to us
• ❌ Advertising identifiers (the App has no ads)
• ❌ Stored location history on our servers
• ❌ Contacts, photos, camera, or microphone data
• ❌ Health or fitness data
• ❌ Social media profiles or logins

3. How We Use Your Information

3.1 Core Functionality

• Determine which Puerto Rico municipio you are in (or near) so we can show the right weather, alerts, sea, river, air, dust, earthquake, and radar information.
• Request that public information from official and public weather services for your area.
• Remember your municipio, units, language, and theme so the App feels like yours.

3.2 The Daily Briefing ("El parte del día")

With Mi Isla Premium, the App's home screen can write a plain-language summary of your day on the island with AI. It is only created when you tap Generate the report, and it is saved on your device for the rest of the day.

To write it, the App sends our AI gateway (a small service we run on Cloudflare) the context the summary needs: your municipio's name, the hour of the day, your language and units, and the day's readings the App already shows you (weather, air quality and Saharan dust, the sea and rivers, active alerts, tsunami status, and recent earthquakes). The gateway passes that request through OpenRouter to an AI model provider (currently a DeepSeek model) and returns the text. Nothing in the request identifies you: no name, account, precise location, or device identifier.

Our gateway does not store the request or the summary. Like any web service, it sees your IP address while handling the request, and uses it only to limit abuse. OpenRouter and the model provider process the request under their own privacy policies. If you are not a premium reader, or never tap Generate the report, nothing is sent.

3.3 Subscription Management

• Verify whether you have Mi Isla Premium so premium features (radar loop and history, extended hourly forecast, full marine swell breakdown, river history, multiple saved locations) unlock.
• Restore your purchase across your devices when you ask to.

We do not use any information to build a profile of you, to advertise to you, or to track you across apps or websites. We cannot — we do not collect it.

4. Location Data

Location is the only sensitive permission Mi Isla requests, so we want to be completely clear about it.

4.1 Turning Location Off

You can revoke location access at any time in your device settings (iOS: Settings → Mi Isla → Location; Android: Settings → Apps → Mi Isla → Permissions). Mi Isla will simply use the municipio you choose manually.

5. Data Storage & Security

5.1 Local Storage

Your data lives on your device:

• On-device database (Drift / SQLite): Cached weather, alert, and conditions responses, plus a small fetch log.
• Device preferences: Your municipio, units, language, theme, and notification choices.
• iOS: Stored in the App's secure sandbox with iOS encryption.
• Android: Stored in the App's private internal storage.

5.2 Network Communication

• All requests to data sources use HTTPS encryption.
• Some public services (for example the U.S. National Weather Service and NOAA) ask apps to identify themselves with a contact string. Mi Isla sends a descriptive identifier — the app name, version, and a contact email — that contains no information about you.
• We do not run our own analytics, logging, or tracking servers.
• The one server we do run is the AI gateway for the premium parte (section 3.2). It does not store or log the requests it handles.

5.3 Data Retention

• Local data: Stays on your device until you clear the App's cache or uninstall the App. We hold no server-side copy to retain.
• Subscription data: Retained by RevenueCat and the app stores per their own retention policies.
• The premium parte: Saved on your device for the day. Our AI gateway keeps no copy; OpenRouter and the AI model provider retain data per their own policies.

6. Public Data Sources

Mi Isla gathers information from official and public weather and geophysical services. When the App requests data for your area, your approximate location (coordinates or area) is sent to the relevant service so it can respond — but never your name or identity, because the App has none to send.

6.1 U.S. National Weather Service (NWS / weather.gov)

• Purpose: The forecast for your area (temperature, feels-like, rain chances, wind, highs and lows) from NWS San Juan, plus official watches, warnings, and advisories.
• Privacy Policy: https://www.weather.gov/privacy

6.2 NOAA (radar, rivers, tsunami.gov)

• Purpose: Radar images from the NWS San Juan radar (opengeo.ncep.noaa.gov), river flow forecasts from the National Water Model (water.noaa.gov), and tsunami status and messages (tsunami.gov).
• Privacy Policy: https://www.noaa.gov/protecting-your-privacy

6.3 U.S. Geological Survey (USGS)

• Purpose: Earthquake data and river gauge levels.
• Privacy Policy: https://www.doi.gov/privacy (U.S. Department of the Interior, USGS's parent department)

6.4 U.S. Environmental Protection Agency (EPA)

• Purpose: The UV Index forecast, requested with your municipio's ZIP code (data.epa.gov).
• Privacy Policy: https://www.epa.gov/privacy

6.5 Mi Isla data files (GitHub Pages)

• Purpose: Air quality, Saharan dust, and wave forecasts, published as small public files at armandojimenez.dev/mi-isla-data and hosted on GitHub Pages. They are built from the Copernicus Atmosphere Monitoring Service (CAMS) and NOAA GFS-Wave forecasts, as processed by Open-Meteo.com. Each file covers all of Puerto Rico, so the request carries no location; your device picks your area itself.
• Privacy Policy: GitHub General Privacy Statement

6.6 RevenueCat (Payments)

• Purpose: Subscription and in-app purchase management.
• Data: Anonymous app user ID, purchase and subscription status.
• Privacy Policy: https://www.revenuecat.com/privacy

6.7 Apple App Store / Google Play

• Purpose: App distribution and processing your subscription payment.
• Privacy Policies: Apple Privacy · Google Privacy

6.8 AI services (premium parte)

• Purpose: Writing El parte del día for premium readers who tap Generate the report.
• Data: Your municipio's name, the hour, your language and units, and the day's readings (see section 3.2). Never your identity, precise location, or a device identifier.
• Path: Our AI gateway on Cloudflare, then OpenRouter, which routes the request to the AI model (currently a DeepSeek model).
• Privacy Policies: Cloudflare · OpenRouter

8. Notifications

With your permission, Mi Isla can send you one daily reminder, at the time you choose, to check in on the island. The App does not watch for alerts in the background to notify you.

• The reminder is scheduled on your device. We do not run a push server, and we do not message you for marketing.
• You can turn the reminder off, or change its time, at any time in the App's settings or in your device settings.
• Mi Isla does not send safety alerts. Because delivery depends on the operating system, the reminder is best-effort and should never be your source for life-safety information. Always rely on official authorities.

9. Your Privacy Rights

9.1 GDPR Rights (European Union)

• Right to Access: Request information about data processing.
• Right to Rectification: Correct inaccurate data.
• Right to Erasure: Request deletion of data.
• Right to Data Portability: Receive data in a portable format.
• Right to Object / Withdraw Consent: Object to or withdraw consent for processing (for example, by revoking location permission).

9.2 CCPA Rights (California)

• Right to Know, Delete, and Opt-Out: We do not sell personal information, and we hold none on our servers to disclose or delete.
• Right to Non-Discrimination: You receive the same App regardless of any privacy choice.

9.3 Exercising Your Rights

Because Mi Isla keeps your data on your device and holds no identity, most rights are immediate:

• Access: Your settings and cached data are visible within the App.
• Deletion: Clearing the App's cache or uninstalling the App removes all local data permanently.
• Location: Revoke location permission in your device settings at any time.

For questions, or about data held by RevenueCat or the app stores, contact us at armando.jimenez.dev@gmail.com.

10. Children's Privacy

Mi Isla is a general-audience weather app and is suitable for users of all ages. It does not require accounts and does not knowingly collect personal information from anyone, including children under 13.

• No accounts or personal identification are collected.
• Parents can use device parental controls and disable in-app purchases.

11. International Users

11.1 Data Processing Location

Mi Isla is focused on Puerto Rico. The public weather services it queries, RevenueCat, and, for the premium parte, Cloudflare, OpenRouter, and the AI model provider may process requests on servers located in the United States or elsewhere. These requests contain only the area information and readings they need, never your identity.

11.2 Regional Compliance

• European Union: GDPR principles respected.
• California: CCPA principles respected.
• Other Regions: We respect applicable privacy laws.

11.3 Language

This Privacy Policy is available in English and Spanish. If there is any conflict between the two versions, the English version prevails.

We may update this Privacy Policy to reflect new features, legal requirements, or changes in the services Mi Isla relies on.

• The "Last Updated" date will be revised.
• Material changes — especially any change to how location or data is used — will be described before they take effect.
• Continued use after an update constitutes acceptance.
